#164 some validation-warnings

[Herr.Vorragend]

mediashare_include_greybox.html
-------------------------------------
Do we need this tag?

<link href="" rel="stylesheet" type="text/css" />

mediashare_browseicons.html
-------------------------------------
HTML-Warning: <img> elements not closed

Example:
<img src="modules/mediashare/pnimages/thumbnails.gif" alt="">

The empty link-tag in 'mediashare_include_greybox.html' generates a validation-error (firebug-console):

Das Stylesheet http://www.domain.de/module-mediashare.htm wurde nicht geladen, weil sein MIME-Typ, "text/html", nicht "text/css" ist.

The same error with shorturls disabled.

I can reconstruct this bug and it disappears after deleting the link-tag in the template.
